ABSTRACT
Two communities have been interested in modeling and predicting human performance. The Human Factors Engineering community has long applied methods for predicting human performance for the purpose of arriving at better designs of systems. For example, past applications have been based on methods and modeling tools such as SAINT and HOS (Elkind, Card, Hochberg, & Huey, 1989; McMillan, Beevis, Salas, Strub, Sutton, & Van Breda, 1989). These approaches are based on analyzing the task that the system operator performs, using systematic task analysis methods that have developed over many years of practical experience in system analysis and design (Beevis et al, 1992; Kirwan & Ainsworth, 1992). In addition, modeling tools use well-established theoretical concepts from human information processing to generate performance predictions. Overall, this approach has been successful enough that considerable effort has been expended to implement computer-based tools for constructing and using models of human performance in system design.
